Maintain maximum water flow around inner building perimeters with our Gutter Internal 90° Angle Commercial. Engineered specifically for 170mm deepflow systems, this internal corner ensures a seamless, watertight transition for large-scale industrial and agricultural roofing projects.
Advanced Flow Dynamics: The deep-seated 170mm profile handles massive volumes of water, preventing overspill at critical corner junctions.
Double-Seal Security: Features pre-fitted, extra-wide EPDM rubber gaskets to provide a permanent, leak-proof seal that accommodates thermal movement.
Industrial Durability: Manufactured from high-impact, UV-stabilized PVC-U to resist warping, cracking, or fading in harsh environments.

A gutter internal 90° angle is a specialized fitting used to navigate the “inside” corners of a building’s roofline. While external angles go around the outside of a structure, the internal 90-degree corner is essential for L-shaped buildings, courtyards, or recessed bays. In a 170mm commercial system, this fitting is designed to manage the high-velocity water runoff typical of expansive warehouse or factory roofs.
At ECO HEAT SHOP, we supply the 170mm system because it offers significantly higher drainage capacity than standard residential guttering. This internal 90° angle is precision-molded to ensure that even when water hits the corner at high speed during a storm, it is funneled efficiently through the system without “backing up.” The deep-channel design is the industry standard for preventing the structural dampness often caused by undersized gutter corners.
Our commercial fittings are manufactured from robust PVC-U, chosen for its excellent strength-to-weight ratio. The fitting includes a secure “clip-lock” mechanism that applies even pressure across the 170mm gaskets. This ensures that the joint remains 100% watertight throughout the seasons, handling the significant thermal expansion and contraction common in long-run industrial guttering.
